Answer:
Firstly, we can state that the net force is the sum of all forces acting upon the object. Since the object is stationary, by Newton's First Law we can conclude that the sum of all forces acting upon a stationary object is 0 because there are no forces acting upon the object.
Explanation:
Please support my answer.
Kinetic energy is formed when water is heated.
Explanation:
- Suppose in an electric kettle there is water , when water is boiled the electrical energy changes into thermal energy when heating is done.
- The thermal energy then gets transferred to the water . When the boiling takes place in the water the energy gets transformed into sound.
- Lastly at the end the gravitational potential energy finally changes to the kinetic energy.
I’m pretty sure it is an object with a net force of zero. All forces are balanced and EQUAL
Answer:
Explanation:
A. And B. solutions are in the attachment.
C.
When the cockroach walks towards the center of the circle, positive work is done so kinetic energy increases.
Answer:
Inertia
Explanation:
Inertia is best defined as the ability of an object to resist a change in position or movement. That is why when an object has a higher mass, the higher the inertia. Imagine an oncoming truck that is fully loaded versus you. The tendency for the truck to change its movement would be difficult because of its its mass. It has a lot of inertia.
